DC Water Nears Containment of Massive Sewage Spill into Potomac River Following Pipe Collapse
WATER INFRASTRUCTURE & DESALINATION
DC Water is nearing completion of containment efforts for a significant sewage spill into the Potomac River, caused by the collapse of a six-foot-diameter pipe that released an estimated 40 million gallons of untreated wastewater daily. Crews have installed six bypass pumps to reroute the wastewater, while testing revealed E. coli levels near the spill were over 12,000 times higher than safe limits for human contact. However, DC Water confirmed that drinking water remains unaffected, as intake points were closed and sourced from upstream areas.
